[SOLVED] Cannot Start httpd - Segfault

34634 · 2013-03-21 23:49:19

Hello,

I am trying to setup Apache but am receiving an error when trying to start the daemon.

The error

/usr/sbin/apachectl: line 84:  7821 Segmentation fault      (core dumped) $HTTPD -k $ARGV

/var/log/messages shows

Mar 21 14:52:53 arch kernel: [  402.544664] httpd[14509]: segfault at 1c ip 00007f1a7b524786 sp 00007fffec1aad70 error 4 in libapr-1.so.0.4.6[7f1a7b506000+2f000]
Mar 21 14:52:53 arch apachectl[14498]: /usr/sbin/apachectl: line 84: 14509 Segmentation fault      (core dumped) $HTTPD -k $ARGV

I've had no luck when researching the issue, but I have found that there are other people with the same error here and here. The difference is that these errors seem to be caused from mod_perl and I do not have that installed.

When trying to start Apache in debug mode, it appears as though all of the modules load before crashing.

Fixed, Apache had issues finding my hostname.

Solution is in the comments https://aur.archlinux.org/packages.php?ID=14141

For those having a problem with xampp segfaulting, this is likely due to it not being able to look up your hostname. For some reason apache is crashing because of this. 

I had to add 

127.0.0.1 hostname.mydomain.com 

to /etc/hosts and now it starts without an issue. 

You can look up your hostname using the hostname command. 

If you want to try and see why it does this you can strace the apache process by doing 

strace /opt/lampp/bin/httpd
